As I've got older, I've had to adjust to the 'cloak of invisibility' slowly descending around me, as the male gaze opts for a younger, fresher target. At first, I felt really sad about it, but as the months have gone on, I've realised that it is one of the most liberating things that has ever happened to me.

Last year I decided to do Christmas alone in London. It felt right - like I could handle it. After three years of either being away on holiday or throwing myself into charity work for Crisis, I thought 'I can do this'. I can be in my flat, on Christmas Day, on my own, and just be.

As for you Demi, your last tweet made me cheer you on even more. 'As a woman, a mother and a wife, there are certain values and vows that I hold sacred, and it is in this spirit that I have chosen to move forward with my life' you tweeted. And that's what we women in our forties are.
